iro of! 'whom it in fig; comer/i lle, it lmown'thnt l, Anonru F. GALL, 'i citizen of the United States, und. u resident ot West Orengo, Essex countyj New Jersey, hure invented ce1-tuin new and useful improvements in Projecting rtppurutus, ol' which the vfollowing is e description.

My invention relates to Projection eppurutus und especially to the menus for controlling,r the posseggo ot light through :1. pro jeetion aperture of n lmnp house or other menus 'for carrying the source of light.

The ohjet't of my invention is the provision ol improved ineens which will insure the closing` of the projection aperture ot' such u device when the lutter is in any posi tion other thun u projecting position, und which will uncover seid aperture when the device is moved into u projecting position.

More specifically described, Inv invention consists in the provision, in u linnp house or other menus 'huvilig the usuel projection :iper-iure und movable, on :1 hed or support into one or more projecting positions. ot' improved shutter Ineens, the shutter of which means-its nornmlly suitably held, preferably hy lhenction of gravity, in n position clos'- ing` the projection zq'ierture; und in the prorieion of improved ineens. Lu'eterniily positioned on snid hed so to automatically nettuno the -shutter means to open the shut trr when the lump house or other means inning the projection aperture is movedi into u projecting position.

Other objects will he disclosed more fully in the followingr description und :appended claims.

In order that my invention may loe netter understood, attention is directed to the uccompnnyinplr drawings, forming e part of this specititmtion, in which the suine reference characters are uned to designute ver responding elements throughout, und in which-m Figure 1 is n. View in side elevation shovfing n lamp house embodying my invention und un operating mechanism t'or movingr und supporting the, film, parts being in new tion; Figs. l und 3 are trent elevations of the lmnp house in different positions on its bed or support; Fig. 4 is n top plan View of :i portion of the larnp house, partly in sec Specification of Letters Extent.

shoun `in Fig. i, the lmnp house being shown, lin full lines, in projecting position with respect to the stereopticon lens, und in dot und dash lines4 in inoperative position.

Reference character 1 designates the lamp house which is provided in its front well with the usual projection aperture 2, und which is inovnbly connected to a hed or support Il in any suitable manner.y es by Z- shnilu-d members el, "i pivoted both to the bed und the hoop house. -t suitable source of light :auch ns n Nr-rust lmnp, `shown diugrtinmutticnily in Fig. l, is mounted in the lump housej und condensing lcnees of the usuel type are mounted edjucent the projection aperture i'. 0n the front of the lamp house, in proximity to the projection aperture 2, in the lens` tube l is :t frame 5 in which is slidably mounted e plate G. The plete tl has e pair ot apertures 7 and 8 :uinpted to be registered with projection aperture 2 for the projection of motion pictures and stereoptieons respectively. Frame .1i is provided with guideways 9 for the reception of lantern slides.

A spring sented ball plunger 11 suitably connected to the lamp house ctfperetes with indentetions '19 provided in e. plate 2G secured to the bed 8 to hold the lamp house yieldingly in any one ot :t plurality of predetermined positions.

For a detailed description of the eppuretus described above` reference is made to my cti-pending application Serial No. 654,223, tiled October l2, i911.

In order to prevent any possibility of njuring the fhn or of igniting the same when inflammable film is used, it is desirable that lthe projection aperture of the lmnp house be closed :it ull times except when it is operatively dined with either of the lenses 17 and 18 of the operating mechanism,L 10, and especially when the lamp house is in its tion und Fig. 5 is a plan View of the device rearward position (as shown in dotted lines actuate saidrod to the lamp house is Y position, substantially as describe open said shutter, when l 10. The combination with a lamp house! moved into lprojecting having a projection aperture, of a bed, means pivotally connecting the lamp house to said bed whereby the lamp house may be moved into and out of a. plurality of projectj ing positions, means com rising a shutter and a rod depending there rom for normally j closing said aperture, and means comprising a plurality of cams on said bed adapted to actuate said rod to open said shutter, when the lamp house is moved into any projecting position, substantially as described. i

11. The combination with a film operating j mechanism having a picture projecting lens, of a bed, a lamp'house having a projection aperture and movably connected with said bed, whereby the lamp house may be moved into and out ofa position in nhich said projection aperture and said lens are operatively alined, means comprising a shutter for closin'g said aperture when the aperture and lens are out of operative alinement, and means on said bed adaptedmutomatically to actuate said first means to open`said shutter when the lamp house is moved to a position j in which said aperture and lens are operatively alined, substantially as described. j

12. The combination with a device proi vided with a projection aperture ,l ed to be moved into and out of a projecting l position, of a source of light carried by said device, and means adapted to operate antoj matically to open and close said aperture when said device is moved into and out of projecting position respectively, substantially as described.

13. The combination with a device provided Witli a projection aperture and adapted to be moved into and out of :1 plurality of prpjecting positions, of a source of light cari and adaptried by said device, and means adapted to operate automatically to open and close said aperture when said device is mover. rito and out of any projecting position respectively, substantially as described.

14. The combination with a projecting dcvice having a projection aperture and adapted to be moved into and out of a projecting position, of means adapted to operate automatically to close said aperture when the projecting device is moved out of projecting position, substantially as described.

15. The combination with a projecting device having a. projection aperture and adapted to` be moved into and out of a plurality of projecting positions, of means adapted to operate automatically to close said aperture when the projecting device is moved out of any of the projecting positions, substantially asidescribed.

16. The combination with a projecting device having a projection aperture and adapted to be moved into and out of a projecting position, of means comprising a member` fo'r closing said aperture and adapted to operate automatically to open said aperture when the projecting device is moved into project ing position, substantially as described.

17. The combination with a projecting device having a projection aperture and adaptcd to be moved into and out of a plurality of projecting positions, of means comprising a member for closing said aperture and adapted to operate automatically to open said aperture when the projecting device is moved into any of the projecting positions, substantially as described.
